APPARATUS FOR TREATING TEXTiLE MATERlALS.

Patented Aug. 21, 1908.

Application filed October 2, 1901. Serial No. 77.275-

To all whom it may concern.-

Be it known that I, ROBERT WEISS, chemist, a citizen of the Swiss Republic, and a resi dent of Kingersheim, Alsace, Germany, have invented new and useful Im rovements in A paratusfor Treating Texti e Materials, of which the following is a full, clear, and exact specification.

My invention relates to a aratus for treating-that is, dyeing, bleac ing, and the like-textile-materials, such as cotton and the like, with circulating superheated liquids, and especially to that class of such apparatus wherein such treatment is effected without causing deterioration of the textile material by the hot vapors. In order to eflect this result, the materials treated must be kept at all times completely immersed in the liquid, and this is attained by disposing the liquid-sup lying vessel whollyabove the tank which contains the textile materials to be treated.

The object of my invention is to provide an improved apparatus of this kind having a device-for reversing the direction of circulation of the liquid through the operating-tank without injuring in any case the above-given conditions of treatment.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is an elevation with some of the parts in vertical section; and Fig. 2 is a sectional view of the four-way cock, showing it turned to a osition different from that seen in Fig. 1, w ere this cock is also shown in section.

In the drawings, 1 represents, a closed tank for reeeivin Y the textile materials to be treated and cal ed hereinafter the operatingtank, 2 a closed vessel containing the supply of liquid provided with the usual appurtenances (such as safety-valve, pressuregage, filling-funnel) and the lower part of which is situated at a higher level than the upper part of the operating-tank l, and 3 a rotating pump for maintaining the circulation of the liquid of treatment,

The pump 3 is connected through its suctionipc 4 with the lower part of the supply vesse 2 and through the pressure-pipe 5 to hand, is connected through a pipe 7 with the upper part of the operating-tank 1, through a pipe 8 with the, lower part of the latter, and through a pi e 9 with the lowerpart of the supply vessel 2. The suction-pifpe 4 of the pump projects into the interior 0 the su ply vessel 2 up to a level situated below the evel of the liquid contained therein.

When the plug of the cock 6 occupies the osition of Fig. 1, the circulation of the liquid is as follows: The liquid passes from the supply vessel 2 through the pipes 4, 5, and 7 into the upper part of the operating-tank 1, leaves the latter on the lower part, and returns through the pipes 8 and 9 to the vessel 2. In the position of the plug of the cock 6 seen in Fig. 2 the liquid passes in the reverse direction through the operating-tank 1, being forced by the pump through 5 8 into the lower part of the operating-tank 1 and leaving the latter on its upper part in order to return through 7 9 to the supply vessel 2. In both cases the pump forces by pressure the liquid through the textile materials in the operating-tank. 4

It will be seen that the textile materials are under all circumstances immersed in the liquid, as even onirregularities of the pum working a minimum level of the liquid wil be created in the supply vessel 2 by the projecting suction pipc 11 is a tube or pipe which in working may be supplied with steam for lieatin the iquid in the vessel 2. This pipe can a so be supplied with cooling Water, as it will be necessary for discharging the a paratus in order to then preserve the textile materials from coming into contact with-hot vapors. 10 is a pressure-regulating air-chamber branched on the forcing-pipe 5 of the pump.

Having now described my invention, what I 'claim is An apparatus for the purpose specified, having a closed tank to receive the materials to be treated, a closed liquid-supplying vessel, the bottom of which is at a higher level than the top of the operating-tank, means for su erheating the circulating liquid, 8. pump for circulating said li uid, a pipe conthe pump with either end of the 0perating-tankntwi1, and

the liquid-supplying Vessel, above the bot- In witness whereof I have hereunto signed tom of this letter vessel and means for. 0011- my name, this 20th day of Se tember, 1901,
